At the pad for R24 on the end that leads to Pin 1 of the RF modulator.

FOIL SIDE

Cut the foil attached to J1, Pin 2.

Cut the foil at the pad for R3 (22K ohm 1/4W resistor) that leads to Pin 1 of the modulator.

INSTALL THE FOLLOWING

COMPONENT SIDE

A 1N914 diode with .250" length of sleeving on the anode lead. Anode lead to the foil leading to Pin 1 of the modulator using the feedthrough hole on this trace. The cathode to the pad for C33 (the pad at the end of the foil leading to R3).

A 1N914 diode across the cut foil of 2.1 above, with the cathode to the pad for R24.

A 2" length of insulated jumper wire from the cathode of diode CR8 to the junction of the foil between R3 and R9.

FOIL SIDE

A 6" length of coax, #RG174/U, stripped 1/4" at each end. Shrink sleeve insulate exposed braid on one end and solder center conductor to J1 Pin 2 (i.e. braid is not connected). Other end solder braid to ground foil at C33 and center conductor to cathode of new diode installed at 3.1.2 above.
